Radial Di Pro D8

A multi-channel DI tailored for keyboard setups and the "rack" logic

The Radial Pro D8 fits into the "pro field" approach: a passive, robust DI designed to simplify wiring and ensure reliable connections when a system becomes complex. Whereas multiple scattered mono DIs multiply power supplies, hum risks, and patching errors, the Pro D8 centralizes 8 channels in a coherent rack format, easy to transport, install, and troubleshoot.

Its "high-density" concept directly addresses the needs of keyboardists and live environments: multiple line sources, sometimes high levels, alternating stereo/mono sounds, and silence requirements between songs. The result: a clear connection base between instruments and console, designed for both the stage and touring racks.

Who is the Pro D8 for, and in which applications does it make a difference?

The Pro D8 is primarily aimed at keyboardists (workstations, stage pianos, synths, expander modules, samplers) and all configurations where multiple line outputs need to be sent in balanced XLR to the front of house and/or monitors. It is also relevant for live production racks, redundant systems (A/B), and stages where a simple, repeatable, and quick-to-check patch is desired.

Each channel offers two passively premixed 6.35mm Jack inputs, allowing you to choose a "performance" logic (stereo summing to a single console channel) or "security" (two ready sources, one DI, immediate switch in case of failure). Additionally, there is a Thru connector for local input monitoring and an effects loop per channel to share the same effects processor between the two inputs of a channel.
